Definitions

  • the present disclosure generally relates to absorbent articles, and more particularly to an absorbent article having an elastic laminate structure, that is smooth, low cost and easily manufactured, for improving fit, aesthetics and leakage resistance.
  • Absorbent articles such as, for example, disposable diapers, adult incontinent pads, sanitary napkins, pantiliners, incontinent garments and the like are generally worn, in cooperation with garments and disposed against a body surface by infants or adult incontinent individuals.
  • the absorbent article is employed to collect and absorb body fluid discharge, such as, for example, blood, menses, urine, aqueous body fluids, mucus, cellular debris and other forms of body discharge.
  • the absorbent article may be disposed between the legs of an individual adjacent a crotch area. The absorbent article is positioned with a garment and drawn into engagement with a body surface of the crotch area to collect body discharge.
  • absorbent articles typically include a fluid permeable coverstock for engaging the body surface, a fluid impermeable backsheet and an absorbent core supported therebetween.
  • the backsheet serves as a moisture barrier to prevent fluid leakage to the garment.
  • the absorbent core usually includes a liquid retention material that faces the body surface.
